PINPOINT TEST B: THE COMPASS IS INOPERATIVE
CONDITIONS DETAILS/RESULTS/ACTIONS
A1 CHECK THE INSTRUMENT CLUSTER VOLTAGE SUPPLY
Instrument Cluster
Using the following table, measure the voltage between the instrument cluster pins, harness side and ground.
IC Connector Pin Circuit
C239 11 1001 (WH/YE)
C240 7 295 (LB/PK)
C240 8 1112 (WH/LB)
 Is the voltage reading greater than 10 volts?
Yes
GO to A2.
No
REPAIR the circuit(s) in question. TEST the system for normal operation.
